    Drilling on an angle other than 90 degrees can be a PITA. Running a spotdrill first would be an absolute must.
    If you're going through hell, keep going.

    Here’s a hand from god

    I’d totally be on something like this, Herron Arms does some excellent custom work!

    Last I checked this is a AR10/AR15 barrel thread. At least you didn’t hijacked this with a shotgun barrel length like the last time..

    Since you brought up the subject...

    Reading comprehension may not be your strong point, so I'll make it explicit: the whole point of the shotgun angle was that a poster was unclear about what constituted barrel length. You may recall they thought it was related to the length of rifling. It wasn't.

    Carry on.

    Another interested person here. Gunner or pencil profile with brake (not FH) preferred.

    yup pencil profile with integrated brake. This would be ideal.

    If they were made with several barrel profiles and brake/hider combinations and they had competitive pricing, I think they'd become the non-restricted standard in this country. I'm also curious how a 17" barrel would do against the 16's and 18's ballistically.

    You only lose about 20 to 50 fps for each inch (in these longer lengths, not for shorties)

    Pretty negligible

    A 16" is about 3178 fps using 55g
    To 3205 at 18.5"

    That's only about 25 fps

    These are approximate numbers as every rifle and barrel and cartridge is a little different but the loss will be comparable pretty much

    Exactly, a 16 inch basically will give you everything youre going to be pragmatically getting out of the 5.56 cartridge anyway.
